Between the cover member 26 and the cylinder 25 fits a sleeve retaining ring 37 corresponding to the ring 30 on the cylinder 23 but the method of retaining this ring inits place is a 'modification of the method of securing the ring 30 in that the ring is threaded to mesh with corresponding threads on the inner wall of the o cover member but either of these forms might be used on either cylinder. The threading might be on the inside of the retaining ring and on the outside of the cylinder instead of on the outside of the ring and the inside of the cover member. These modifications are so very evident that it has not been thought necessary to show them in the drawings. The sleeve retaining rings allow the sleeve packing to be readily removed at any time and new pack` ing` rings inserted.

f the sleeve retaining ring were. omitted, it would be practically impossible to machine av cover member for two or more cylinders to produce' tight joints between this member and the cylinder. The distance between the joints of the cover member and the 'cylinder at the top and bottom must be exact and'even7 if it were possible to 'ma- 'chine these joints absolutely exactly, the difference in thickness of the packings would render one of the joints imperfect. The sleeve retaining ring is movable parallel to the axis of the cylinder and can therefore be adjusted to make a perfect it se that it is unnecessary to have the machining exact. With the sleeve retaining ring, the packing for the'ito edge of the sleeve may be seated in a g oove in this rin when it is not desirable to have this packing 1n the sleeve. If no sleeve retaining ring were used it would be necessary to form a groovein the covermember. To form such .a groove in tl'lej'c'ove'r member and obtain perfect packing would be an exceedingly difficult matter.

Iln the embodiments of the invention hereinbefore described the cylinders have been cast in block but when these cylinders are ca'stseparately, it is particularly important that they be properly spaced in order that the sleeve driving gears may mesh properly'. ln Figs. 4 and 8 is shown a cylinder retain- 'ing plate 38 having formed therein loops 38 and' 38l which lit over the cylinders.

This plate acts as a bearing plate for the sleeves and as an oil basin to permit the gears on the sleeves and the sleeves themselves to be properly oiled and to ferm an oil seal at the bottom edge of the sleeves. The oil Hows about in the depressed surface or channel 39, Fig. 8 shows a plan of this plate 38 detached. f more than two cylinders are used the number of loops in this plate would correspond with the'number of cylinders. The

madera oil is forced up onto this plate 38 by the oil pump and overow means may be provided.

In the embodiment shown in Fig. 7 the '19 is provided an oil pump 46 which is here of the intermeshing gear type. By driving the valves from the lay shaft instead 0f from the crank shaft as is usually customary, a single shaft driven by a spiral gear operates the valves and the oil pump and thus a small number of shafts and gears are necessary.

The applicant is aware that a considerable number of changes in the construction and arran ement of parts may be madA by anyone silled in .the artwithout departing from the scope of his invention and therefore he does not care to be limited to the particular embodiments herein shown and described.
